Deprecation of the Insecure Hedera Consensus Service (HCS) Mirror Node Endpoints

Hedera is committed to enhancing the security and reliability of its services. As part of this effort, we are deprecating the insecure Hedera Consensus Service (HCS) mirror node endpoints. The legacy endpoints hcs.<env>.mirrornode.hedera.com:5600 will transition to the new secure <env>.mirrornode.hedera.com:443 endpoints. This change impacts developers, exchanges, wallets, and SDK users relying on the old gRPC port 5600.
